AMI BIOS
1-1 Introduction
This chapter describes the AMIBIOS for the Intel 430 TX chipset
which is designed for an Intel Pentium ® 75/90/100/120/133/150/
166/180/200/233 MHz, Cyrix/IBM 5x86, 6x86, AMD-K5, AMD-K6 and
MMX TM processors. The AMI ROM BIOS is stored in the Flash
EEPROM and is easily upgraded using a floppy disk-based program.
System BIOS
The BIOS is the basic input output system used in all IBM ® PC,
XT™, AT ®, and PS/2 ® compatible computers. The WinBIOS is a
high-quality example of a system BIOS.
Configuration Data
AT-compatible systems, also called ISA (Industry Standard Architecture) must have a place to store system information when the
computer is turned off. The original IBM AT had 64 bytes of nonvolatile memory storage in CMOS RAM. All AT-compatible systems
have at least 64 bytes of CMOS RAM, which is usually part of the
Real Time Clock. Many systems have 128 bytes of CMOS RAM.
How Data Is Configured
AMIBIOS provides a Setup utility in ROM that is accessed by
pressing <Del> at the appropriate time during system boot. Setup
configures data in CMOS RAM.

Description
The number for a drive with certain identification parameters.
The number of cylinders in the disk drive.
The number of heads.
Write
Precompensation
The size of a sector gets progressively smaller as the track
diameter diminishes. Yet each sector must still hold 512 bytes.
Write precompensation circuitry on the hard disk compensates for
the physical difference in sector size by boosting the write
current for sectors on inner tracks. This parameter is the track
number where write precompensation begins.
Landing Zone
This number is the cylinder location where the heads will normally
park when the system is shut down.
Sectors
The number of sectors per track. MFM drives have 17 sectors
per track. RLL drives have 26 sectors per track. ESDI drives
have 34 sectors per track. SCSI and IDE drive may have even
more sectors per track.
Capacity
The formatted capacity of the drive is (Number of heads) x
(Number of cylinders) x (Number of sectors per track) x (512
bytes per sector)

Chapter 2: Running Setup
These options specify which bus the specified IRQ line is used on
and allow you to reserve IRQs for legacy ISA adapter cards. If more
IRQs must be removed from the pool, the end user can use these
options to reserve the IRQ by assigning an ISA/EISA setting to it.
Onboard I/O is configured by AMIBIOS. All IRQs used by onboard I/
O are configured as PCI/PnP.
IRQ14 and 15 will not be available if the onboard PCI IDE is enabled. If all IRQs are set to ISA/EISA and IRQ14 and 15 are allocated to the onboard PCI IDE, IRQ 9 will still be available for PCI
and PnP devices. This is because at least one IRQ must be available for PCI and PnP devices.
The settings are ISA/EISA or PCI/PnP. The Optimal and Fail-Safe
default settings are PCI/PnP, except for IRQ 12.
Reserved Memory Size
This option specifies the size of the memory area reserved for
legacy ISA adapter cards. The settings are Disabled, 16K, 32K, or

The system can be configured so that all users must enter a password every time the system boots or when the WINBIOS setup is
executed. You can set either a Supervisor password or a User
password. If you do not want to use a password, just press <Enter> when the password prompt appears.
The password check option is enabled in the Advanced Setup by
choosing either Always or Setup. The password is stored in CMOS
RAM. You can enter a password by typing the password on the
keyboard, selecting each letter via the mouse, or selecting each
letter via the pen stylus. Pen access must be customized for each
specific hardware platform.
When you select Supervisor or User, AMIBIOS prompts for a password. You must set the Supervisor password before you can set
the User password. Enter a 1-6 character password. The password does not appear on the screen when typed. Retype the new
password as prompted and press <Enter>. Make sure you write it
down. If you forget it, you must drain CMOS RAM and reconfigure
the system.

Appendix A
Hard Disk Error Messages
The first group of errors listed below may appear during the
initialization process, before anything else happens.
1.
No Hard Disk Installed — The program could not
find a hard disk drive installed on the system. This
message appears if there is no hard disk on the
system and you have chosen to run the Hard Disk
Utility.
2.
FATAL ERROR Bad Hard Disk — The program is
not getting a response from the hard disk, or the
hard disk is not repairable. Check all cable and
power connections to the hard disk.
3.
Hard Disk Controller Failure — The program is getting
an error response from the reset command
sent to the hard disk controller. Check to see that
the controller is seated properly in the bus slot.
4.
C: (D:) Hard Disk Failure — The hard disk drive (C or D)
is not responding to commands sent to it by the
program. Check power and cable connections to the
hard disk.
A-1
SUPER P5MMA98/P5MMS98/P5MMA2/P5MMS2 User’s Manual
NOTE
The errors listed below may appear during operation.
5.
Undefined Error - Command Aborted — An error
condition has occurred which the program cannot
identify.
6.
Address Mark Not Found — The address mark (initial
address) on the hard disk could not be found.
7.
Requested Sector Not Found — The sector currently
requested on the hard disk could not be found.
8.
Reset Failed — The program issued a reset command
to the hard disk, but this command did not properly
reset the hard disk.
9.
Drive Parameter Activity Failed — The program has
sent a reset command to the controller, followed by
the drive parameters. Using the parameters sent to
it, the controller is not getting a response from the
hard disk drive. Check to see if the drive type
selected in the ‘Standard CMOS Setup’ is correct for
the disk drive being used.
10.
Bad Sector Flag Detected — The program has tried to
perform an operation on a sector which has been
flagged (i.e., marked as “bad”).
11.
Bad ECC on Disk Read — When the program attempts to
write to the disk, it also calculates an ECC (Error
Correction Code) value for the data being written.
This ECC value is written to the drive and then read
back. If the value read back is different from the one
calculated, then, this error will occur.
A-2
Appendix A:
Hard Disk Error Messages
12.
ECC Corrected Data Error — The ECC value
(explained above) read from the disk is not the same
value which was written to the disk; therefore, the
program assumes that the data is not correct. It,
then, attempts to correct the data, but the ECC value
is not corrected. In this situation, this message
appears.
13.
Controller Has Failed — The program has issued a
diagnostic command to the controller, which has
failed; therefore, the controller has failed as well.
14.
Seek Operation Failed — The program has issued
a seek command to the drive and this operation has
failed. A seek operation is the act of finding a
particular sector on the hard disk.
15.
Attachment Failed to Respond — No response has
been received from the hard disk drive. This
message appears if an operation has already begun
and the hard disk does not respond, when it has
responded earlier.
16.
Drive Not Ready — The program is trying to perform an
operation on the hard disk drive, and it has waited
beyond a preset specified time limit. This situation
is known as “timeout.”
17.
Write Fault on Selected Drive — A ‘Write Fault’ has
occurred during the write operation on the hard disk.

BIOS Error Beep Codes
During the POST (Power-On Self-Test) routines, which are
performed each time the system is powered on, errors may occur.
Non-fatal errors are those which, in most cases, allow the system
to continue the boot-up process. The error messages normally
appear on the screen. See Appendix E for BIOS Error Messages.
Fatal errors are those which will not allow the system to continue
the boot-up procedure. If a fatal error occurs, you should consult
with your system manufacturer for possible repairs.
These fatal errors are usually communicated through a series of
audible beeps. The numbers on the fatal error list below
correspond to the number of beeps for the corresponding error. All
errors listed, with the exception of #8, are fatal errors.

NOTE
If the “Wait for <F1> If Any Error” option in the
Advanced CMOS Setup portion of the BIOS SETUP
PROGRAM has been set to “disabled,” the <Fl>
prompt will not appear on the third line.
For most of the error messages, there is no ERROR Message Line

Message the text will be “RUN SETUP UTILITY.” Pressing the <F1>
key will invoke the BIOS SETUP PROGRAM.
A description of the error messages appears below.
1.
CH-2 Timer Error — Most PC AT™ standard system
boards include two timers. An error with timer #1 is
a fatal error, explained in Appendix C. If an error
occurs with timer #2, this error message appears.
2.
INTR #1 Error — The interrupt channel #1 has failed
the POST routine.
E-1
SUPER P5MMA98/P5MMS98/P5MMA2/P5MMS2 User’s Manual
3.
INTR #2 Error — The interrupt channel #2 has failed
the POST routine.
4.
CMOS Battery State Low — There is a battery in
your system which is used for storing the CMOS
values. This battery appears to be low in power and
needs to be replaced.
5.
CMOS Checksum Failure — After the CMOS values
are saved, a checksum value is generated to provide
for error checking. If the previous value is different
from the value currently read, this error message
appears. To correct this error, you should run BIOS
SETUP Program.
6.
CMOS System Options Not Set — The values stored
in the CMOS are either corrupt or nonexistent. Run
the BIOS SETUP Program to correct this error.
7.
CMOS Display Type Mismatch — The type of video
stored in CMOS does not match the type detected by
the BIOS. Run the BIOS SETUP Program to correct
this error.
8.
Display Switch Not Proper — Some systems require
that a video switch on the motherboard be set to
either color or monochrome, depending upon the
type of video you are using. To correct this situation,
set the switch properly. (Remember to shut down
the system first.)
9.
Keyboard is Locked...Unlocked It — The keyboard
lock on the system is engaged. The system must be
unlocked to continue the boot-up procedure.
E-2
Appendix E:
BIOS Non-Fatal Error Messages
10.
Keyboard Error — The BIOS has encountered a
timing problem with the keyboard. Make sure you
have an AMI keyboard BIOS installed in your system.
You may also set the ‘Keyboard’ option in the BIOS
SETUP Program, Standard CMOS Setup to “Not
Installed,” which will cause the BIOS to skip the
keyboard POST routines.
11.
KB/Interface Error — The BIOS has found an error
with the keyboard connector on the system board.
12.
CMOS Memory Size Mismatch — If the BIOS finds
the amount of memory on your system board to be
different from the amount stored in CMOS, this error
message is generated. Run the BIOS SETUP
Program to correct this error.
13.
FDD Controller Failure — The BIOS is not able to
communicate with the floppy disk drive controller.
Check all appropriate connections after the system is
powered off.
14.
HDD Controller Failure — The BIOS is not able to
communicate with the hard disk drive controller.
Check all appropriate connections after the system is
powered down.
15.
C: Drive Error — The BIOS is not receiving any
response from hard disk drive C. It may be
necessary to run the Hard Disk Utility to correct this
problem. Also, check the type of hard disk selected
in the Standard CMOS Setup of the BIOS SETUP
Program to see if the correct hard disk drive has
been selected.
16.
D: Drive Error — The same error has occurred with
hard drive D. Follow the procedures in Error #15 to
correct the situation.
E-3
SUPER P5MMA98/P5MMS98/P5MMA2/P5MMS2 User’s Manual
17.
C: Drive Failure — The BIOS cannot get any
response from the hard disk drive C. It may be
necessary to replace the hard disk.
18.
D: Drive Failure — The same error as #17 has
occurred with hard drive D.
19.
CMOS Time & Date Not Set — Run the ‘Standard
CMOS Setup’ of the BIOS SETUP Program to set the
date and time of the CMOS.
20.
Cache Memory Bad, Do Not Enable Cache! — The
BIOS has found the cache memory of the
motherboard to be defective. Consult your system
manufacturer to repair this problem.
21.
8042 Gate A20 Error — The Gate A20 portion of
the keyboard controller (8042) has failed to operate
correctly. The 8042 chip should be replaced.
22.
Address Line Short! — An error has occurred in
the address decoding circuitry of the motherboard.
23.
DMA #2 Error — An error has occurred with the
second DMA channel on the motherboard.
24.
DMA #1 Error — An error has occurred with the
first DMA channel on the motherboard.
25.
DMA Error — An error has occurred with the DMA
controller on the motherboard.
26.
No ROM BASIC — This error occurred when a proper
bootable sector cannot be found on either the floppy
diskette drive A: or the hard disk drive C:. The BIOS
will try at this point to run ROM Basic, and the error
message will be generated when the BIOS does not
find it.
E-4
Appendix E:
BIOS Non-Fatal Error Messages
27.
Diskette Boot Failure — The diskette used to bootup in floppy drive A is corrupt, which means you
cannot use it to boot-up the system. Use another
boot diskette and follow the instructions on the
screen.
28.
Invalid Boot Diskette — The BIOS can read the
diskette in floppy drive A, but it cannot boot-up the
system with it. Use another boot diskette and follow
the instructions on the screen.
29.
* On Board Parity Error — The BIOS has
encountered a parity error with some memory
installed on the system board. The message will
appear as follows:

Where XXXX is the address (in hexadecimal) where
the error has occurred. “On Board” means that it is
part of the memory attached directly to the system
board, as opposed to memory installed via an
expansion card in an I/O bus slot.
